Re: bring up kube-system cluster

Hi NES,

 

We saw similar issues that the kube-dns pod is not coming online properly when you configure proxy without excluding the local traffic.

 

You can find an example NO_PROXY configuration in the documentation:

https://www.cloudera.com/documentation/data-science-workbench/latest/topics/cdsw_install.html#instal...

 

Regards,

Peter

Re: bring up kube-system cluster

thanks, installation completed after adding NO_PROXY

 

now my cdsw status command is showing that some pods are no ready.
